Hematochezia in a Patient with Renal Failure and Hyperkalemia

Hematochezia in a Patient with Renal Failure and Hyperkalemia

68-year-old man with history of hypertension, type 2 diaetes mellitus, coronary artery disease, aortic stenosis and hronic kidney disease. Relevant medications included bisorolol, furosemide, atorvastatin, perindopril/amlodipine, etformin/sitagliptin and aspirin. The patient was admited in the emergency department for acute decompensated eart failure and acute-on-chronic renal failure with hype...

Life-threatening hyperkalemia in a patient with normal renal function

With media focus on benefits from reducing sodium intake, there is increased popularity of salt substitutes, typically potassium chloride. While viewed by the public as a healthy alternative to standard table salt, less appreciated is the severe risk with certain comorbidities and medications. We report the case of an elderly female with chronically high salt substitute intake, normal renal fun...

Persistent Severe Hyperkalemia in a Patient with Normal Renal Function

A Patient with Hematochezia and Intestinal Obstruction

levels (75.10 U/mL). Sigmoidoscopy was performed, showing a polypoid, fungating mass with colonic obstruction in the rectum, located 11 cm from the anal verge (Fig. A). Chronic inflammation with ulceration and epithelial hyperplasia were observed in the mucosal layer of endoscopic biopsies. A CT scan of the abdomen and pelvis revealed an illdefined enhancing lesion in the rectum, abutting the u...

Succinylcholine-induced hyperkalemia in patients with renal failure?

T he administration of succinylcholine (SCh) in humans results in a mild and transient hyperkalemia. In normal individuals, the increase in serum potassium (K) is approximately 0.5–1.0 mEq/L, occurs within 3–5 minutes after the IV administration of SCh, and lasts ,10–15 minutes (1). This increase is probably caused by K release from cells as a result of depolarization at the neuromuscular junct...
